Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return fmt fmt = "%.3f" -> return fmt fmt =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib

Find end-of-line. Return pointer will point to either first \n, either str_end.

API is designed this way to avoid exposing the 4K page size e.g. use with IsGlyphRangeUnused(0, 255)

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.
